<section>
	<h2>Purpose</h2>
	<p>Dynamically generates charts and graphs from table data.</p>
	<p>This feature dynamically generates charts from table data. The table data used to generate the graphic need to have a structure as defined in the techniques for tables. The graphic generated can be easily customized by using the CSS Option set to the tables elements.</p>
	<p>The Charts plugin is an interface between a data table and a drawing charts engine. Currently, for extensibility and to ease support, <a href="https://www.flotcharts.org/">Flot</a> is the charts drawing engine used.</p>
</section>

<section>
	<h2>Use when</h2>
	<ul>
		<li>To publish simple or complex charts online</li>
		<li>Before using an image-based charts approach</li>
		<li>To save time in creating long text descriptions for your charts</li>
		<li>To have uniform charting style across your website</li>
	</ul>

	<h2>How to implement</h2>
	<ol>
		<li>Organize your chart's data into a table.
			<p>Tips: You can use the techniques for designing tables</p>
		</li>
		<li>Add a <code>class=&quot;wb-charts&quot;</code> element to the table.
			<pre><code>&lt;table class=&quot;wb-charts&quot;&gt;</code></pre>
		</li>
		<li>Quickly customize your chart by adding predefined preset, via CSS class name, to the table.
			<pre><code>&lt;table class=&quot;wb-charts wb-charts-bar&quot;&gt;</code></pre>
			or to series header.
			<pre><code>&lt;tr&gt;
	&lt;th class=&quot;wb-charts-bar&quot;&gt;
	[...]
&lt;tr&gt;
	&lt;th class=&quot;wb-charts-line&quot;&gt;
	[...]</code></pre>

	<h2>Tips and trick</h2>
	<section>
	<h3>Add floating labels to pie charts</h3>

	<ol>
	<li>Add the <code>wb-charts-slicelegend</code> class to the chart table
		<pre><code>&lt;table class=&quot;wb-charts wb-charts-slicelegend table&quot;&gt;</code></pre>
	</li>
	<li><strong>Optional:</strong> Add <code>data-flot</code> to customize label positioning and label for combined slices.<br>
	<ul>
		<li><code>"label": { "threshold" }</code> defines the percentage share of the pie slices that will be hidden (ranging 0 to 1) i.e. '0.3' will hide all slices 3% or less of the total. Default is '0.05' (5%).</li>
		<li><code>"combine": { "threshold" }</code> defines the percentage of pie slices that are combined to a single slice (ranging 0 to 1) i.e. a value of '0.03' will combine all slices 3% or less into one slice. Default is '0.05' (5%).</li>
		<li><code>"combine": { "label" }</code> defines the label text of the combined slice. Default is "Combined slice" and "<span lang="fr">Quartier regroupé</span>".</li>
	</ul>
	<pre class="mrgn-tp-md"><code>&lt;table class=&quot;wb-charts wb-charts-slicelegend table&quot; data-flot='{
	"series": {
		"pie": {
			"label": {
				"threshold": 0.05
			},
			"combine": {
				"threshold": 0.05,
				"label": "Combined slice"
			}
		}
	}
}'&gt;</code></pre>
	</li>
	</ol>
	</section>

	<section>
	<h3>Bypass the data cell value on table parsing</h3>
	<p>This method should be only used as a last resort when the text Content of the data cell can't be parsed as a numerical value which would be understood when drawing the charts.</p>
	<p>Add on a table cell the attribute <code>data-wb-charts-value</code> and its value would get parsed by the regular expression to extract the value and the unit.</p>
	<pre><code>
&lt;td data-wb-charts-value="200$"&gt;two hundred dollars&lt;/td&gt;</code></pre>
	</section>

	<section>
	<h3>Increase white space between series</h3>
	<p>The following data-flot option can be use to simulate more spacing between each series.</p>

	<pre><code>&lt;table class=&quot;wb-charts&quot; data-flot='{ &quot;bars&quot;: { &quot;lineWidth&quot;: 0.2, &quot;show&quot;: true } }'&gt;</code></pre>

	<p>The result could look like the following visualization.</p>

	<table class="wb-charts table" data-flot='{ "bars": { "lineWidth": 0.2, "show": true } }'>

	<h3 id="functionpreset">Using functions with a custom preset</h3>
	<p>Supported version: This is supported by all WET 4 version.</p>
	<p>Goal: Extracting and parsing custom tabular data to create your chart or graph. If you need just to set plain options, take a look at the <a href="../../../demos/charts/piecustom-en.html">Customizing pie charts</a> working example.</p>
	<section>
		<h4>Declaring your custom preset function</h4>
		<pre><code>&lt;script&gt;
window[ "wb-charts" ] = {
	charts: {
		<strong>custom</strong>: {
			fn: {
				&quot;/getcellvalue&quot;: function(elem){
					var raw = $(elem).text().replace(/\s\s+/g, ' ').replace(/^\s+|\s+$/g, '').replace(/N/g, '');
					return [parseFloat(raw.match(/[\+\-0-9]+[0-9,\. ]*/)), raw.match(/[^\+\-\.\, 0-9]+[^\-\+0-9]*/)];
				}
			}
		}
	}
};
&lt;/script&gt;</code></pre>

		<p>The key for the <code>fn</code> object is similar to the JSON pointer defined in <a href="https://datatracker.ietf.org/doc/html/rfc6901">RFC 6901</a>. The key identifies what should be overwritten with the function.</p>

		<p>You can rename "custom" by anything you want, just keep in mind of that placeholder name will be the same name for your CSS custom option.</p>

		<script>
		window[ "wb-charts" ] = {

	<h4>Going beyond</h4>

		<p>The previous functionality allowed you to set any javascript function to better control <a href="https://github.com/flot/flot/blob/master/PLUGINS.md">flot plugin</a> and to the call back defined in the <a href="https://github.com/flot/flot/blob/master/API.md">flot API core</a>.</p>


		<p>The following examples show you how you can control the <a href="https://www.flotcharts.org/flot/examples/series-pie/index.html">pie chart</a> label formater. Note that the context has been changed to target directly the flot options.</p>

		<h5>Custom pie chart label formater, code example</h5>
		<pre><code>&lt;script&gt;
window[ "wb-charts" ] = {
	<em>flot</em>: {
		<strong>mylabelformater</strong>: {
			fn: {
				&quot;/series/pie/label/formatter&quot;: function( label, series ) {
					var textlabel;
					if ( !optionsCharts.decimal ) {
						textlabel = Math.round( series.percent );
					} else {
						textlabel = Math.round( series.percent * Math.pow( 10, optionsCharts.decimal ) );
						textlabel = textlabel / Math.pow( 10, optionsCharts.decimal );
					}

					return label + &quot;&lt;br /&gt;&quot; + textlabel + &quot;%&quot;;
				}
			}
		}
	}
};
&lt;/script&gt;</code></pre>

		<p><code>&lt;table class=&quot;wb-charts <strong>wb-charts-pie wb-charts-mylabelformater</strong> table&quot;&gt;</code></p>

		<h5>Custom pie chart type, code example</h5>
		<p>The same result is produced in this example, but the functionality of the 'pie' chart is inherited using the option named <strong>base</strong>. By doing this, you create a new chart type based on the pie chart while including your customized settings.</p>
		<pre><code>&lt;script&gt;
window[ "wb-charts" ] = {
	flot: {
		mycustompie: {
			<strong>base: "pie",</strong>
			fn: {
				&quot;/series/pie/label/formatter&quot;: function( label, series ) {
					var textlabel;
					if ( !optionsCharts.decimal ) {
						textlabel = Math.round( series.percent );
					} else {
						textlabel = Math.round( series.percent * Math.pow( 10, optionsCharts.decimal ) );
						textlabel = textlabel / Math.pow( 10, optionsCharts.decimal );
					}

					return label + &quot;&lt;br /&gt;&quot; + textlabel + &quot;%&quot;;
				}
			}
		}
	}
};
&lt;/script&gt;</code></pre>

		<p><code>&lt;table class=&quot;wb-charts <strong>wb-charts-mycustompie</strong> table&quot;&gt;</code></p>

		<h5>Mixing two contexts</h5>
		<p>You can push you configuration even further by mixing two contexts of settings like <em>flot</em> and <em>charts</em>. When called, the options of both contexts will be applied.</p>

		<pre><code>&lt;script&gt;
window[ "wb-charts" ] = {
	<em>flot</em>: {
		<strong>mysuperconfig</strong>: {
			base: "pie",
			fn: {
				&quot;/series/pie/label/formatter&quot;: function( label, series ) {
					var textlabel;
					if ( !optionsCharts.decimal ) {
						textlabel = Math.round( series.percent );
					} else {
						textlabel = Math.round( series.percent * Math.pow( 10, optionsCharts.decimal ) );
						textlabel = textlabel / Math.pow( 10, optionsCharts.decimal );
					}

					return label + &quot;&lt;br /&gt;&quot; + textlabel + &quot;%&quot;;
				}
			}
		}
	},
	<em>charts</em>: {
		<strong>mysuperconfig</strong>: {
			fn: {
				"/getcellvalue": function(elem){
					var raw = $(elem).text().replace(/\s\s+/g, ' ').replace(/^\s+|\s+$/g, '').replace(/N/g, '');
					return [parseFloat(raw.match(/[\+\-0-9]+[0-9,\. ]*/)), raw.match(/[^\+\-\.\, 0-9]+[^\-\+0-9]*/)];
				}
			}
		}
	}
};
&lt;/script&gt;</code></pre>

		<p><code>&lt;table class=&quot;wb-charts <strong>wb-charts-mysuperconfig</strong> table&quot;&gt;</code></p>

	<h3>Other customization for your chart</h3>
	<ul>
		<li>Configure the plugin using the <code>data-wb-charts</code> on the <code>table</code> element. This parameter allows you configure the options on how your data table will be interpreted in a programmatically determined way.
			<pre><code>&lt;table class=&quot;wb-charts table&quot; data-wb-charts='{ &quot;referencevalue&quot;: 1, &quot;labelposition&quot;: 1, &quot;noencapsulation&quot;: true }'&gt;</code></pre>
		</li>

		<li>Configure the plugin using the <code>data-flot</code> on the <code>th</code> element
			<pre><code>&lt;!-- The following example configure a specific color for a series --&gt;
&lt;th data-flot='{&quot;color&quot;:&quot;#56E&quot;}'&gt;</code></pre>
		</li>

				<td><code>wb-ready.wb-charts</code> (v4.0.5+)</td>
				<td>Triggered automatically after a chart initializes.</td>
				<td>Used to identify which chart was initialized (target of the event)

			<tr>
				<td>passiveparse.wb-tableparser</td>
				<td>When the charts need the table parser to parse the table. When this event is triggered, the Flot library is loaded. You can also take advantage of this event to load your own Flot plugin. </td>
				<td>It will parse the data table and attach the information to a data attribute named tblparser on every element that is related to the table.</td>
			</tr>
			<tr>
				<td>parsecomplete.wb-tableparser</td>
				<td>When the table parser has completed its parsing job.</td>
				<td>Indicates that the tblparser data attribute is now ready to be used. It is after this event that the data will be prepared for Flot. Then the charts will be created.</td>
